Geospatial Data

BART station locations (centroid), station entrances and rail lines are provided free of charge in both KML and KMZ format. Keyhole Markup Language (KML) is an XML notation for expressing geographic annotation and visualization, and KMZ is a compressed version the KML.



 We have a few requests

  • Register and sign a super-long agreement
    Psyche: we don't do that here. We won't make you jump through hoops to use BART open data. Just follow our short and simple Developer License Agreement, give our customers good information and don't hog community resources. If that doesn't work, we can start managing usage with keys and writing more terms and conditions. But who wants that?
  • Keep your work up to date
    Things will change. When they do we'll try to give you plenty of notice through the opt-in email list.
  • Don't use the official BART logo or system map
    Only we get to use official BART trademarks and copyrighted works to let customers know they're getting info directly from BART versus one of the tons of other places that use BART open data. (If you need a BART system map for your project, check out our editable App Map with a CC-By license).
  • Don't forget about us
    Give us a shout out or a link back and let us know about the cool stuff you're doing.

Frequently Asked Questions

  • Will you help me troubleshoot?
    Sorry. If we help you, it's only fair that we help everyone else, too. We simply don't have the resources for that. But you can always ask questions to the unofficial BART Developers Google Group.
  • What are your plans for future development?
    All of our developer services are created on what we call "BART one percent time." In that context, we're doing our best to add new features, fix problems and keep it all going. Drop us a line if you have any suggestions.
